WILLIAM ARTHUR TEMPLE, OF KNOXVILLE, IOWA.

FOUR-HORSE EVENER.

Specification of Letters Patent.

Patented Dec. 22, 1908.

Application filed March 18, 1908. Serial No. 422,568.

To all whom it may concern:

Be it known that I, WILLIAM ARTHUR TEMPLE, a citizen of the UnitedStates, residing at Knoxville, in the county of Marion and State ofIowa, have invented a new and useful Four-Horse Evener, of which thefollowing is a specification.

The object of my invention is to provide a four-horse evener adapted tobe detachably and reversibly applied to a right hand or left hand plowto facilitate the operation of the plow as required to plow deep in softor hard ground without undue fatigue or straining of horses and asrequired to allow one horse to walk in a furrow and the other threehorses to walk on unbroken ground.

My invention consists in the construction, arrangement and combinationof parts as hereinafter set forth, pointed out in my claim andillustrated in the accompanying drawings, in which:

Figure 1 is a plan view that shows my invention applied to the beam of aright-hand plow in such a manner that one horse can walk in a furrow andthe other three on unplowed ground. Fig. 2 is a horizontal sectionalview looking forward from the line was of Fig. 1 and shows the relativepositions of the overlying parts.

The numeral 10 designates a draw bar provided with an aperture at itsrear end to admit a clevis 12 as required for detachably connecting itwith the front end of a plow beam 13 as shown in Fi 1 A reversible mainevener 14 is ivotaIly connected with the front end of t e draw bar 10and two mating curved bars 15 jointly and pivotally connected inoverlying position with the short arm of the evener 14 to extend outwardover the end of the evener and forward therefrom at their curved ends.

It is obvious that by extending the curved bars 15 inwards to near thedraw bar 10 the doubletree connected therewith will retain swingletreeson opposite sides of the line of advance occupied by the draw bar insuch a manner that only one horse will be on one side of the line of thedraw bar to walk in the furrow and three horses as hereinafter setforth, allowed to walk on the unbroken ground or sod when the plow is inoperation.

A link or straight bar 16 is pivotally connected with the straight endsof the bars 15 and the rear end of the draw bar 10.

A doubletree 17 is pivotally connected with the long arm of the evener14 and a second doubletree 18 with the overlying curved front ends ofthe mating bars 15 and swingletrees 19 are pivotally and detaohably asshown, or in any suitable way, as required for hitching horses thereto.

In the practical use of my invention one horse can walk in the furrowpreviously made and the other three on the unbroken ground and applytheir force evenly to the plow beam as required to advance a plowforward in a straight line.

To change the evener from a right hand plow to a left hand plow the drawbar 10 must be detached from the right hand plow and inverted and thenconnected with the beam of the left hand plow.

It is obvious my invention can be applied to other objects or machinesto be advanced.

Having thus set forth the purposes of my invention, its construction andmanner of use, the practical operation and utility thereof will beobvious.

What I claim as new and desire to secure by Letters-Patent, is

A four horse evener for plows comprising a draw bar, means forconnecting the draw bar to a plow beam, a reversible main evener, twocurved bars pivoted to the end of the short arm of said evener, a linkconnecting said curved bars with the rear end of the draw bar, an evenerconnected with the free ends of said curved bars to carry swingletreeson the opposite sides of the line of the draw bar, an evener connectedwith the long end of the main evener and four swingletrees arranged andcombined for hitching four horses to a plow as set forth, for thepurposes stated.
